Most Common Traumatic Cycling Injuries

Shoulder

A break in the collar bone of the shoulder (clavicle – figure 1) usually due to a fall off the bike onto the point of the shoulder or outstretched arm, or, from a forceful direct impact directly to the clavicle. Associated with severe shoulder pain, tenderness on firmly touching the affected region of the bone and sometimes swelling or a bony deformity.

Elbow & Forearm

A break in the radius or ulna bone (figure 6) usually due to a fall from the bike onto an outstretched hand. Associated with severe pain usually located in the forearm that may radiate into the wrist, hand, elbow or upper arm, in addition to swelling, tenderness on firmly touching the affected region of the bone, markedly reduced wrist and elbow function and sometimes bony deformity. Pain typically worsens when trying to use the hand brakes on the bike or upon weight bearing through the affected wrist.

Wrist & Hand

A break in the radius bone near the wrist (figure 6) usually due to a fall from the bike onto an outstretched hand. Associated with severe pain usually located on the thumb side of the wrist that may radiate into the thumb, hand or forearm, in addition to swelling, tenderness on firmly touching the affected region of the bone, markedly reduced wrist function and sometimes bony deformity. Pain typically worsens when trying to use the hand brakes on the bike or upon weight bearing through the affected wrist.

Most Common Overuse Cycling Injuries

Areas of the body which are particularly prone to overuse cycling injuries, most of which can be attributed to incorrect or poor bike setup, include the knees, lower back, upper back and neck. Some of the more common overuse cycling injuries include:

Knee

An overuse injury to the under surface of the knee cap which typically presents as pain at the front of the knee. Pain may be particularly noticeable whilst in heavier gears, standing out of the saddle, walking down stairs, hopping, kneeling, lunging, squatting or landing from a jump. Associated with pain on firmly touching the patellofemoral joint (i.e. edge of the knee cap – figure 8) and occasionally a grinding sensation behind the knee cap.

Back & Neck

Tearing of connective tissue surrounding a disc in the lower back with subsequent bulging of disc material (figure 12). Typically as a result of repetitive or prolonged bending forwards of the lower back (e.g. cycling), during sitting, lifting or twisting or following trivial movements, such as picking up a pencil or sneezing. May cause lower back pain centrally or on one or both sides of the spine, with or without symptoms radiating into the buttock, groin, thigh, lower leg, ankle or foot. Pain may increase on firmly touching the affected level of the spine and there is often associated muscle spasm and restricted spinal movement. Occasionally there may be no lower back pain, with only symptoms down the affected leg. Pins and needles or numbness are occasionally present in the affected leg or foot. Symptoms often increase with riding long distances, repetitive or prolonged sitting, bending, lifting, coughing or sneezing and are often worse first thing in the morning.

Wrist & Hand

Narrowing of the tunnel in the wrist formed by connective tissue (the flexor retinaculum) and the small carpal bones of the wrist, resulting in compression of structures within the carpal tunnel, such as the median nerve (figure 14). Typically occurs due to repetitive or prolonged gripping activities (e.g. cycling and heavy use of the hand brakes) or general use of the hand. Can be aggravated by poor bike setup relating to handle bar and seat position. Associated with a pain or ache in the wrist that may radiate into the hand, fingers or forearm and often pins and needles or numbness in the fingers (excluding the little finger). Symptoms are often worse first thing in the morning and pain may increase during gripping or lifting activities or during general use of the hand. Pain may also increase on firmly touching or tapping the median nerve at the front of the wrist (Tinel’s test – figure 15) and this may cause pins and needles or altered sensation into the fingers.

Injury Prevention Tips for Cycling Injuries

Bike Setup

Many overuse cycling injuries can be prevented (or successfully managed) by ensuring a correct bike setup for riding. Correct bike setup may also help to minimise the likelihood of traumatic cycling injuries by improving stability and therefore reducing the risk of falls or collisions. To learn more about saddle height, saddle position, seat angle, posture length, handle bars and cleat alignment, read our helpful tips in Bike Setup.

Bike Condition

It is vital to maintain your bike in good working order. Get your bike serviced regularly to ensure it is safe and secure.

Footwear

Ensure your cleats are properly adjusted and check them regularly. If you are not used to wearing clip-on cleats, practice in a safe environment before taking to the roads.

Technique

A common technique error with long distance cycling is pedalling in too low a gear. Protect your knees and prevent leg fatigue by keeping the revolutions per minute (rpms) of your pedals between 60 and 110. Cycling in heavier gears and pedaling slowly places undue stress on the knee joints.

Ride safely

This includes:

Riding to your own ability level

Riding appropriately to the conditions

Leaving enough room from the cyclist in front of you so that if they stand up (which pushes their bike back underneath them) they won’t overlap your front wheel.

Staying alert, always, even on familiar routes

Keeping your eyes on the road ahead

Having regular breaks to rehydrate, re-energise and to minimise fatigue
